POTATO :FEELING AND WASHING MACHINE.

Application iled September To all whom it may concern:

Be it known that l, SAMUEL ROYLANCE, a citizen of the United States,residing at New Bedford, in the county of Bristol and State ofMassachusetts, haveinvented certain new and useful Improvements inPotato Peeling and Washing Machines, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to potato peelers and washers and one of theprincipal objects of the invention is to provide a simple and efficientdevice of this type whereby quantities of potatoes may have their skinsremoved rapidly and effectively and the potatoes thoroughly washed sothat all skins, dirt and foreign matter are removed within a minimumspace of time.

A further object of the invention is the provision of a machine of thischaracter in which all of the parts may be readily. removed one from theother so that all parts may be thoroughly cleansed to keep the machinein a perfectly sanitary condition.

Further objects of the invention will appear as the following specicdescription is read in connection with the accompanying drawings whichform a part of this application and in which:

Figure 1 is a front elevation;

Figure 2 is a side elevation;

Figure 3 a top plan view with the hopper cover removed;

Figure 4 a vertical sectional view taken centrally through the machine;and

Figure 5 a detail vertical sectional view showing the method ofproducing the abrading projections.

Referring more particularly to the drawing, C generally represents thecasing andv T the top thereof which, as shown in Figure 4, is providedwith a depending flange 1 to engage within the upper section of thecasing As shown in Figure 4, the casing C is constructed of independentsections 2 and 3 both tubular in form and preferably constructed ofsheet metal of suitable gauge which is treated to prevent corrosion inany preferred manner, for instance, such as galvanizing. The lowersection has a bottom 4 and secured thereto and projecting laterallytherethrough .are a plurality of lugs 5 through which attaching meansare passed for securing the machine to the floor or other availablesupport. The upper sec- Serial No. 498,957.

` tion 3 of the casing is, as shown in Figure 4, provided with aninwardly and downwardly extending annular flange 6 adapted to enter theupper end of the section 2 so as to hold the sections 2 and 3 in properaligned position and support the section 3 upon the upper edge of thesection 2.

Secured to the bottom 4 centrally thereof is a step bearing 7 andmounted in this bear` ing is the end of a driven shaft 8. extendedupwardly to a point slightly above the upper edge of the section 2 whereit has removably keyed thereto a potato supporting base 9 circular inoutline to conformito the inner contour of the casing and which isprovided with abrading projections 10, the construction of which willhereinafter be described.` The upper end of the shaft, as shown inFigure 4, is mounted in a cross bar or spider 11 which carries a bearing12 coacting with a similar bearing 13 to support a drive shaft 14 in aposition horizontal or at right angles to the driven shaft 8. The shaft14 carries at one end afbelt pulley 15 which may be connected to anysuitable source of power and at the inner end the shaft 14 has securedthereto a toothed pinion 16 which meshes with a correspondingly toothedbeveled gear 17 keyed to the shaft 8 by a set screw 18 or in any othersuitable manner.

Removably secured within'the upper section 3 in spaced relation theretobut concentric with the interior of the section is an abrading cylinder19 provided with the abrading projections 20 similar to the projections10 on the base 9 which are adapted to be engaged by the potatoes toremove the skin and dirt therefrom, as will be presently described. Theupper section 3 is pro` vided with a door 21, closing an opening22'formed in the casing, and this door carries a spaced section which isremovably attached to the door and provided with abrading projectionssimilar to those indicated at 10 and'20. This section 23 fills anopening 24 formed in the abrading cylinder 19 so as to make the cylindercontinuous during the operation of peeling and skinning the potatoes.The door is latched in cle-.sed position by a pivoted latch member 25engaging a suitable keeper 26 on the side of the section 23. Secured tothe casing imi being properly peeled and washed. From the chute thepotatoes may be discharged into any suitable receptacle such as acooking vessel or the like.

ln order to properly wash the potatoes l provide a movable spray head 28which may be directed into the lia-red upper end 29 of the top T duringthe time t-hat the potatoes are being peeled so as to wash all skins anddirt therefrom through the openings formed in the abrading projectionsand between the bottom et the abrading cylinder and the potatosupporting base 9. l also provide a second tienib y lonnected nozzle 30by which a stream or water may be directed into all parts of theabrading cylinder and associated parts to thoroughly cleanse them of anyaccumulated skins or dirt.

In order that the water utilized to wash the potatoes may not haveaccess to the gears, l provide a receiving pan 3l .having an annularperipheral flange 32 which has a lateral extension 33 arranged tooverhang the upper edge or the section 2, as clearly shown in Figure 4f.ln position, this pan 31 is supported immediately below but spaced awayfrom.. 'the reif'olving base 9 and is centrally apertured, as indicatedat 3l, to receive the shaft 8. The pan is also provided with a dischargespout 35 which may be connected to the sewer in any suitable manner, ormay discharge the wash water into any suitable receptacle, as is foundmost desirable.

As shown in Figure 5, l form the abrading projections l0 and 2O on therevolving base 9 and cylinder 19 by punching up the metal to producecrater like projections 36 having central apertures 3?' and annularroughened edges 38 which effectively act upon the potatoes to removeskins, dirt and any foreign matter which may adhere thereto.

In the operation of the device, a quantity of potatoes are dumped intothe llared upper end 29 oi' the top T falling upon the revolving base 9which is continuously revolved through the medium of the shaft 14, shaft8 and associated gears. The potatoes on the revolving base 9 are rapidlyturned over and thrown by centrifugal action into with the abra/dingprojections on the cylinder 19 where they are further acted upon by theprojections 2O to remove all skins and foreign matter. During thisoperation Vor immediately following the saine, as is found mostdesirable, but preferably while the potatoes are in motion, the sprayfrom the nozzle 28 is discharged on to the potatoes with such torce asto er'lfectively wash all particles of skin and dirt removed iroin thepotatoes by the abrading projections through the openings 37 and throughthe space between the lower end ot the cylinder and the revolving baseinto the pan 3l 'from whence they are discharged through the nozzle 35into a receptacle or sewer as may be found desirable.

lt will thus be seen that l have provided a very simple and etlicientmachine whereby large quantities of potatoes may have their skins andforeign matter removed therefrom in an effective and rapid manner, thusmaking the machine a very desirable adjunct to hotel kitchens and likeplaces where large quantities of potatoes are peeled and washed at onetime.

l/Vhat l claim is:

ln a potato cleaning machine, a casing constructed or upper and lowerseparable tubular sections, the upper section having a flange extendinginto the upper end ofthe lower section, abrading rmeans arranged in theupper section and including a revolving supporting and abrading disk, avertical shatt arranged in the lower section and en` gaged with saiddisk to rotate the same,l means carried in the last named section :torrotating the shaft, and means arranged intermediate the sections Vforpreventing particles removed rom'the potatoes from contacting with theoperating means including a pan having an annular peripheral flangeslidably fitting the interior of the upper end 'o'l the lower section,said flange having at its outer end a lateral extension overhanging thelower edge of the upper section, the interior of said {lange slid-ablyreceiving the liange of the upper section.

ln testimony whereof I hereunto aiiix my signature. y

SAMUEL ROYLANCE.
